MAGAZINE FIRE-ARM.

ZJPECIFICATION forming part of Letters Patent No. 305,093, datedSeptember 16, 188%. Application filed February 26, 1883. (N0 model.)

To all whom, it may concern.-

Be it known that I, WM. Mason, of New Haven, in the county of New Havenand State of Connecticut, have invented a new Improve ment in MagazineFire-Arms; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a longitudinal central section through the receiver, barrel,and magazine, showing a side view of the mechanism of the arm, a portionof the breechpiecc broken away to show the firing-pin retractor lever;Fig. 2, a top view; Fig. 8, a longitudinal section showing the parts inthe condition of having just received the cartridge from the 1nagazine;Fig. 4, the same section showing the breech-piece as having completedthe first part of its ascent, and presenting the cartridge in line withthe barrel; Fig. 5, a horizontal section through the month of themagazine; Fig. 6, a view of the extractor, the magazinelatch, and thelever to force the cartridge on to the breech-piece; Fig. 7, ahorizontal section showing the side-loading opening and its cover; Fig.8, an outside view; Fig. 9, an edge view of the cover; Fig. 10, atransverse section on line a: w of Fig. 1, looking toward the front.

This invention relates to an improvement in magazine fire-arms, theobject of the inven tion being to adapt to magazine-arms in a practicalmanner that class of breech-piece commonly known as swinging downwardand backward that is to say, a breech-piece hung in the frame in rear ofthe barrel, and so that its forward end swings downward and backward inopening, and returned upward and forward to its position of closing; andit consists in the construction and arrangement of mechanism of the arm,as hereinafter described, and more particularly recited in the claims.

A represents the receiver, constructed to contain the mechanism of thearm, and provided with a tang, B, at its upper rear end and tachment ofthe receiver to the stock; D, the barrel, secured to the receiver; E,the magazine, arranged beneath and parallel with the barrel, and so asto open through the front end of the receiver in the usual manner formagazine-arms; F, the breech-piece, hung in the receiver at the rearupon a pivot a, 'so as to turn freely up and down from the position seenin Fig. 1 to that seen in Fig. 3 and return. WVhen in its up positionits forward face is directly in rear of the barrel, and so as to standagainst the head of the cartridge, to resist recoil. When it is down, asseen in Fig. 3, its upper surface is in a position to receive a newcartridge from the magazine, to be transferred to a position in linewith the barrel, and when in that position the cartridge is forcedforward into its place in the barrel. Then the breeclrpiece continuesits upward movement to a position in rear of and so as to support thecartridge thus transferred.

G is the lever by which the breech-piece is operated. Said lever is hungon a pivot, b, in the lower part of the receiver, the lower armextending rearward to form the triggerguard, and a suitable handle bywhich the lever may be operated. Above the pivot b is an arm, H, which,when the breech-piece is in its closed position, stands against ashoulder, (2, on the breech-piece, and thus acts as a brace to supportthe breech-piece in its closed position. From the rear end of thebreechpiece an arm, I, extends downward, and into the path of ashoulder, e, 011 the lever G, said shoulder being above thepivot.Between the arm I and the shoulder d on the breech-piece thebreech-piece is recessed, as seen in Fig. 1. The first movement of thelever in opening the breech-piece is for the brace H to escape from theshoulder d on the breech-piece and into the recess in rear of saidshoulder, as seen in broken lines, Fig. 1. So soon as the brace H hasescaped from the shoulder (Z the shoulder e at the rear strikes the armI on the breechpiece, turns that arm to the rear, and thus 9 causes thebreech-piece to be turned down until the upper surface of the recess inthe breech-piece strikes the end of the brace H. Then the brace willpass onto a shoulder, z,

a like tang, C, at the lower rear end, for the at- I on the arm I, and,continuing its movement,

tridge raised to the breech-piece until the breech-piece is raised willturn the breech-piece to its extreme dow n.- ward position, as seen inFig. 3, and which position is that of receivinga cartridgefrom themagazine. Returning the lever, the first part of its movement raises thebreech-piece into the position seen in Fig. 4, to present the cartridgein line with the barrel. The upper side of the recess in the breechpiece between the shoulder d and the arm I is substantially the arc of acircle of .which the pivot b, on which the lever turns, is the center,so that while the brace H is passing forward through the recess, andupon this curved surface, the breech-pie'ce will remain stationary togive an opportunity to transfer the carthat position into the barrel,and when the cartridge has been so transferred then the arm or brace Hstrikes the forward end of the recess, and, actingas a cam, completesthe upward movement of the breechpiece and passes into itslocking-position, as seen in Fig. 1.

To automatically transfer the cartridge from the breech-piece, a lever,L, is hung near the bottom of the receiver, in front of the lever G, andupon a pivot, f. This lever extends up through a slot in thebreech-piece and works forward and back in the slot in the breech piece,as from the position in Fig. 1 to that seen in Fig. 3. Forward of itspivot a spring, g, is applied, the tendency of which is to throw thelever L rearward. The rear face of the lever L above the pivot is shapedas seen in Figs. 3 and 4, and upon this face rides an antifrietion roll,h, in the lever G, this roll arranged forward of the pivot b, so that asthe lever is turned down in opening the roll rides upward on the rearface of the lever L. Standing as seen in Fig. 1, the nose of the lever Lis in rear of the forward face of the breech-piece. In opening thebreech-piece the friction-roll h passes up on the rear face of the leverL until it reaches the back of said lever. Then the lever is free toturn rearward by the ac-' tion of its spring 9, and as the openingcontinuesthe lever L turns to its extreme rear position, as seen in Fig.3, resting upon the roll h. At this time thenose Z of the lever is atthe rear end of the breech-piece, and so that as the cartridge passesfrom the magazine onto the breech-piece its head will strike the nose I,as seen in Fig. 3. Then in returning the lever to'raise thebreech-piece, as before described, the breech-piece rises until thecartridge, is in line with the barrel, .as seen in Fig. 4. During thismovement of the breechpiece and the lever G no effect is had upon thelever L, the shape of the back of the lever being such that, it retainsthe said relation to to present the cartridge to the barrel, as beforedescribed. When arrived at this point, as seen in Fig. 4, theanti-friction roll it on the lever G strikes the back of the lever L,and throws it quickly forward to the position the spring g, one end tothe lever L, the other end slotted G, as shown, represented I seen inbroken lines, Fig. 4, the nose 1 of the lever L carrying the cartridgeforward and into its place in the barrel. At this time the lever L hasarrived at its extreme forward position and the arm or brace H hasarrived to the position on the breech-piece, so that further movement ofthe lever G will causethe breech-piece to rise; but as the nose of thelever L stands forward in the position to be occu pied by the forwardpart of the breech-piece it is necessary to withdraw the nose of thelever L to a certain extent,or so as to come within the slot in thebreech-piece. The length of the back of the lever L is therefore suchthat as soon as the lever L has forced the cartridge into the chamberthe anti-friction roll it will escape from the back and pass onto therear face of the lever L. That rear face is out forward, as at m, so asto permit the lever L to recede as the locking lever advances andbreech-piece rises, and into the position seen Fig. 1, and just as theparts come into their normal condition, as seen in Fig. 1, a notch orrecess, a, on the lever L passes onto the antifriction roll h by theforce of the spring and thus the spring serves to temporarily retain thelever and the operative parts of the arm in their normal'condition.

' To insure the extreme rear movement of the lever L, and without entiredependence upon I introduce a link, M, hung by and hung to the lever asupon the same pivot which supports the anti-friction roll h.

To prevent the cartridge, which has passed from the magazine onto thebreech-piece, a finger, N, is hung upon the same pivot a as thebreech-piece, and so as to lie close upon thetop of the breechpiece whenthe breech'piece is up, as seen in broken lines, Fig. 1. Upon the underside of the hub of the finger N is a cam, 0, upon which a spring, P,bears, so that the action of the spring upon the cam tends to turn thefinger downward upon the breech-piece, and so that during the first partof the downward movement of the breech-piece the finger N follows thebreech-piece, because of the action of the spring P; but so soon as thefinger has passed down to about the line of the bore of the barrel ashoulder, r, the end of the spring P, as seen in Fig. 3, which arreststhe farther descent of that fingeri' The breech-piece, continuing itsdescent, opens or passes away from the finger, soasto form a spacebetween the upper surface of the breech-piece and the finger, as seen inFig. 3, into which the cartridge will pass. Then as the breech-piece israised, with the cartridge between it and the finger N, the spring bearsupon the cam-surface 0 and holds the finger N down upon the top of thecartridge, so as to retain the cartridge in its place until the lever Ladvances and forces the cartridge from between the finger N, and thebreech-piece. Then the finger N is free to return to its place theaccidental displacement of comes in contact with upon the breech-piece.The upper'surface of the finger N is curved downwardly, as seen in Fig.3, and forms a chute leading directly into the cartridge-chamber of thebarrel, so that when the breech-piece is down, if it be desirable, acartridge may be introduced into the chamber of the barrel, over thefinger N as a guide, and as it would be introduced into a breech loadingarm of this same class of breech-piece.

R is the firing-pin, arranged longitudinally through the breech-piece,so that its points will stand at the proper position to strike theprimer, and its rear end in position to receive the blow of the hammerT, in substantially the usual manner for communicating the blow of thehammer to the cartridge.

To withdraw the fi ri ng-piu before the breechpiece commences itsdescent, a lever, t, is hung in the arm I of the breech-piece upon apivot, to, its nose standing in a notch, w, in the firing-pin. Theforward face, 2, of this lever projects beyond the face of the arm I,upon which the shoulder e of the lever operates, and so as to receivethe action of that shoulder e before it will reach the face of the armI, as seen in Fig. 1, and so thatthe movement of the lever to unlock thebreech-pieee will turn the lever 15 rearward and withdraw the firingpinbefore the shoulderecomes in contact with the arm I to turn thebreech-piece downward, as seen in broken lines Fig. 1. The play of thelever t is limited by a slot or enlarged hole, 3, through which a pin,4, in the arm I passes. This leaves the firing-pin free when thebreechpiece is closed.

To extract the cartridges a bell-crank lever is hung upon a pivot, 5, inthe lowerpart of the receiver, one arm, 6, extending up, so as to standin front of the flange of the cartridge when the parts are in theirnormal condition, as seen in Fig. 1. The other arm, 7, extends rearwardinto the path of movement of the breeclrpiece, and so that as thebreech-piece descends from the position seen in Fig. 1 to that seen inFig. 3 the breech-piece will strike the arm 7 and turn the arm 6rearward, and thereby extract and eject the cartridge, substantially asin the usual bell-crank extractors.

As a check for cartridges in the magazine, so that as one passes ontothe breech-piece the next will be caught and prevented from passing sofar to the rear as to interfere with the movement of the breeeh-piece, alatch, 8, is hung upon the same pivot, 5, as the extractor, its noseextending upward and so as to work in a slot in the lower side of themagazine. \Vhen the extractor is forward, as seen in Fig. 1, its hubstrikes the back of the latch 8 and turns it downward, so that its nose9 is below or flush with the inner surface of the magazine; but so soonas-the extractor starts in its ejecting movement it leaves the latchfree to rise under the action of the spring 10. It therefore will notinterfere with the passage of the extreme rear cartridge onto thebreechpiece when. that comes into line; but so soon as that cartridgepasses onto the breech-piece thelatch rises and will engage the nextcartridge, as seen in Fig. 3, and hold it until the breech-piece againrises. Then the latch will be thrown down, permitting the cartridgewhich it caught to pass over it and stand in position seen in brokenlines, Fig. 1, ready to pass upon the breech-piece when next itdescends.

WVhile the spring of the magazine can usually be depended upon to throwthe cartridge onto the breecl1-piece,.to provide against any defect inthis respect I arrange a lever, 11, upon the pivot 5, its arm extendingup at the side of the magazine opposite the side-loading opening. Thearm is elastic, and in its normal condition stands in aslot, 12, made inthe receiver at the side of the magazine, (see Fig. 5;) but as it passesfrom the magazine-that is, fro m the position seen in Fig. l to thatseen in Fig. 3its elasticity will cause it to spring inward, as seen inbroken lines, Fi 5, and come forward of the flange of the cartridge, asseen in Fig. 5. It is thus turned forward by means of an arm, 13, whichis struck by the breech-piece in its descent, as seen in Fig. 3. In themovement thus imparted to the arm 11 it first comes into a positionforward of the flange of the cartridge, and then, acting upon theforward side of the flange of the car tridge, serves to impart to thecartridge a quick and'strong rear movement, suffieient to throw thecartridge to its place on the breechpiece. IVhen the breeelrpiecereturns, a shoulder on the hub of the extractor strikes this lever andreturns it to its place. The mouth of the slot 12 being inclined, asseen in Fig. 5, the arm is forced outward as it passes .into the slot12, so as to permit the next cartridge to pass rearward,- ready toreceive the impulse, as before.

The extractor lever, the latch, and the forked lever 11 are showndetached in Fig. 6.

The magazine may be charged when the breech-piece is down by depressingthe finger N, the spring P yielding for that purpose, as seen in brokenlines, Fig. 3. In that case the latch 8 engages each cartridge as itenters the magazine, the elastic arm 11 yielding for the head of thecartridge to pass it; but as a side loading is preferred by many, Imakean opening, 14, upon the right-side of the receiver, through which thecartridges may pass to the magazine when the parts are in their normalcondition, and as a cover for this opening I arrange a slide, 15, asseen in Fig. 7. This slide is provided with a tailpiece, 16, whichextends forward into a slot, 17, provided for it in the receiver, theforward end of the tail constructed with a diagonal slot, 18, throughwhich a vertical pin, 19, extends as a pivot, upon which the cover willwork, the slot permitting longitudinal movement of the cover, asindicated in broken lines, Fig. 7. The forward end of the cover isinclined outward, as at 20, and rides upon a shoulder, 21, at theforward end of the opening in the receiver, and so that by moving thecover forward the inclined surface 20 rides upon the shoulder 21 andturns the nose of the cover outward, so as to open the passage to themagazine, as seen in Fig. 7.' Upon the inside of the cover is a spring,22, the tendency of which is to hold the cover 'in its closed position,but yields so that as the cover is moved forward it will open. as beforedescribed, the slot 18 permitting such forward movement. Therefore tocharge the magazine it is only necessary to press the point of thecartridge against the rear end of the cover with sufficient force toslide the cover forward. Then the cartridge will readily pass throughthe opening into the magazine, and when the magazine is properly chargedthe cover may be returned by the hand of the operator, or the action ofthe spring 22 may be such as to throw it forward and make it toautomatically close.

The firing-pinis made fiat uponits two sides, and the lever L is forked,one leg of the fork working each side of the firing-pin, as seen in Fig.10, and to permit the free working of the lever L through the brace orarm II, that arm is also made forked, one part standing each side of thelever L, as seen in said Fig. 10, the friction-roll standing between thetwo parts of the brace, as indicated in Fig. 10,

there being a shoulder, d, on the breech-piece at each side tocorrespond to the said parts of the brace.

If the magazine be charged from above only, and without the sideopening, the ejector may have an arm upon both sides, so as to engagethe head of the cartridge at opposite points, and the lever 11 may alsohave two arms, so as to operate upon both sides of the cartridge.

While I prefer to hinge the finger N upon the same pivot as thebreech-piece, it may be hung directly to the breechpiece independent ofthat pivot. I

While I prefer to make the follower which forces the cartridge from thetop of the breechpiece into the barrel in the form of the lever L, asdescribed, other followers may be employed to force this transfer. Itherefore do not wish to limit the peculiar movement and operation ofthis breech-piece to this precise construction for the follower.

While I prefer to operate the breech-piece by means of a lever formed asa part ofthe trigger-guard, and have thus shown and described theinvention, it will be understood that any of the known equivalents forthe said triggerguard lever may be employed. Therefore by the termlever, as applied to the operation of the breech-piece, I wish to beunderstood as including any of the known equivalents whereby thebreech-piece may be operated.
